You can put this solution on YOUR website!
You add the 12 and the 24 to get 36. You can't combine that with the radical term. So the answer
\n" ); document.write( "to this problem is that the perimeter P of this triangle is:
\n" ); document.write( ".
\n" ); document.write( " $\"P+=+12+%2B+24+%2B+12%2Asqrt%283%29+=+36+%2B+12%2Asqrt%283%29\"$
\n" ); document.write( ".
\n" ); document.write( "And that's all you can do with it unless you want to find a \"just about\" answer. You could do
\n" ); document.write( "that by using a calculator to find the square root of 3. Then multiply that square root by 12.
\n" ); document.write( "Once you get that answer you add 36 and you get the answer of:
\n" ); document.write( ".
\n" ); document.write( " $\"P+=+56.78460969\"$
\n" ); document.write( ".
\n" ); document.write( "But that's not the exact answer. It's very, very, very close to exact. The more accurate answer is:
\n" ); document.write( ".
\n" ); document.write( " $\"P+=+36+%2B+12%2Asqrt%283%29\"$
\n" ); document.write( ".
\n" ); document.write( "You were right ... you can't add the radical term directly to the integers.
\n" ); document.write( ".
\n" ); document.write( "Hope this helps you to understand the problem ...
